The Digital Public Library of America (DPLA), Stanford University, and DuraSpace will foster a greatly expanded network of open-access, content-hosting "hubs" that will enable discovery and interoperability, as well as the reuse of digital resources by people from this country and around the world. At the core of this transformative network are advanced digital repositories that not only empower local institutions with new asset management capabilities, but also connect their data and collections. Currently, DPLA's hubs, libraries, archives, and museums more broadly use aging, legacy software that was never intended or designed for use in an interconnected way, or for contemporary web needs. The three partners will engage in a major development of the community-driven open source Hydra project to provide these hubs with a new all-in-one solution, which will also allow countless other institutions to easily join the national digital platform.
